Hi,

we are observing build failures on conda-forge for GLPK 5.0. The used
build instructions are in brief:

```
cd w%ARCH%
copy config_VC config.h
 
:: Get the major minor version info (e.g. `4_60`)
python -c "import os;
print('_'.join(os.environ['PKG_VERSION'].split('.')[:2]))" > temp.txt
set /p MAJ_MIN_VER=<temp.txt
 
nmake /f Makefile_VC
nmake /f Makefile_VC_DLL
 
copy glpsol.exe %LIBRARY_BIN%
copy ..\src\glpk.h %LIBRARY_INC%
copy glpk.lib %LIBRARY_LIB%
copy glpk_%MAJ_MIN_VER%.dll %LIBRARY_BIN%
copy glpk_%MAJ_MIN_VER%.dll %LIBRARY_BIN%\glpk.dll
 
if errorlevel 1 exit 1
```

Which will error out with the following on the Azure runner:

```
glpk_5_0.def : error LNK2001: unresolved external symbol glp_netgen_prob
glpk_5_0.lib : fatal error LNK1120: 1 unresolved externals
```

A full log and definition of the runner can be found at https://dev.azur

Thanks for your help!
